The perfect thick, creamy sandwich topper made with egg yolk, mustard flour and vinegar.

In a mixing bowl, combine the egg yolk, mustard flour, and vinegar. Whisk them together until well blended.

Prepare the Base

Slowly drizzle in the vegetable oil while continuously whisking. Start with just a few drops and gradually increase the amount as the mixture begins to thicken.

Add Oil Gradually

Once the mayonnaise starts to thicken, add salt and lemon juice. Continue to whisk until the mixture is smooth and creamy.

Incorporate Seasonings

If the mayonnaise is too thick, you can add a few drops of water or additional vinegar to reach your desired consistency.

Adjust Consistency

Transfer the mayonnaise to a clean jar and store it in the refrigerator. It should be used within a week.
